Pengenalan Produk

The filter differential pressure sensor receives one pressure line from each side of a HEPA filter, prefilter or air-handling coil. Its low-pressure element converts the difference into a continuous signal that rises as resistance builds at a given airflow. Monitoring systems can trend the value and generate a maintenance alarm before the filter causes excessive fan demand or airflow loss. Clearly separated high and low ports, colored tubing and serviceable zero adjustment reduce common installation errors.

Ciri-ciri Utama

Dual pressure taps isolate filter resistance from the surrounding duct static level.

Continuous output shows the rate of loading instead of only a single switch point.

Adjustable alarm and hysteresis support planned maintenance before severe restriction.

Colored pressure lines and labeled ports reduce upstream-downstream connection errors.

Kebimbangan Produk Pelanggan

Filter pressure drop depends on airflow as well as loading, so reliable interpretation requires correct pressure connections and trend context.

Maintenance changes filters on a fixed schedule without knowing actual loading.Continuous differential trends reveal how resistance develops under real operation.

Reversed pressure tubes produce a negative or misleading reading.Red-blue tubing and marked high-low ports preserve upstream-downstream orientation.

A brief fan-speed change triggers a false dirty-filter alarm.Delay and hysteresis prevent a short airflow transition from being treated as sustained loading.

A damaged or missing filter creates an unexpectedly low pressure drop.Low-differential alarms can identify probable bypass or absent media as well as high loading.
